To all whom it may concern Be it known that I,4 J. SIEfRIsT, of the city, Vdounty, and State of New York, have invented a new useful 4Improvement in Stop-Motions for Warpin'g and the following is a full; clear, reference being had `to the accompanying drawing, forming part of this speciication, and in w hich Figure l represents a longitudinal sectional elevation of-a warping-machine in part, with my improvement-applied to it ;l n

Figure 2, a partly sectional plan of the same; and Figure 3, a transverse sectional elevation, taken as indicated by the lines a: in figs. 1 and z2, and looking in direction or the arrow Similar letters of reference 'indicate corresponding This, myimprovement, has reference to warping'-1 machines, for either broad or narrow weaving, applicaf blealso more directly to looms andother'machines.

My invention differs from other devices for effecting a similarobject, as applied, for instance, to braidingmachines, and in which weights have been hung on or attachedto the warp-yarns, so that in case of a yarn breaking or. running out, the weight in dropping would actnate a'stop-nfotion to "the machine, by combining with Weights, so applied and operating, a peculiar stopmotion, made up oi' a balance-trame and rods or le`vers, so combined and arranged with a revolving shaft or drum, carrying a projection, as that, in case of a yarn breaking or running out, the balance-name, by the action of said projection, is made to trip or relieve a belt-shifter in such manner as that, by the' shifting of the belt, it throiws the yarn-beam out of ge'ar.

Referring to the accompanying drawing, A A is an upright frame, sustaining, among its other` uses, rods, B B, which niay be made off glass or other polished material, and over which the yarns a c pass from bobbins, C C, -to the yarn-beam D, that revolves in beardiierent disposition and increased numberof bobbins used to what is or are here shown. y

The frame A A also serves to carry` guide-plates, F F, which are perforated to admit of 4the passage through them of rods or weights, G G, that are looped 'or hooked on to the yarns a a, between the rods B B, which arrangement keeps the rods G G independently suspended until the yarns that pass through their eyes or loops break, or the 'spools that supply said 'yarns are run out. i

VH is a horizontal board, 1ying beneath the weights G G, and connected, by arms b b, with a rock-shaft, I. that is hung to work lightly and easily in side-bars or name-pieces c c.

- balanced frame, and causing On the shaft I, adjustable, it may be,'by a set-screw d, is a slotted arm or lever,"J, which has connected with it, also in an adjustable manner, a rod that may be supported .at 'its' outer end by a cord, c, from any fixture, or otherwise.

These devices, namely, board H, with its rock-shaft I, and arm and rod-attachments J K, constitute-what maybe termed a balance or nearly-balanced frame.

y When said frame is balanced, or at rest, the outer or forwardend ofthe bar K extends or projects into close proximity to a revolving shaft or drum, L, and so that a slight forward movement, of said barcause's it to be struck by a projection, f, attached to a revolving drum, L, that'serves, through belt, todrive the yarn-beam D.

On the shan', of this drumv L are fast and loosepulleys h It', the fast one, h, of which serves, by belt'from any suitable prime or counter-mover, to give motion to `said drum, and'through it to the'yarn-beam D.

M is anupright slotted bar, firmly secured -to the frame.

N is a lever, attached to the belt-shifter O, and having pivoted to it an .arm or lever, P, which passes through the slot in the bar M, and by a stepped projection, k, to it, gears with the slotted bar M, so as to keep the driving-belt on the fast pulley h.,

R vis a spring, arranged to pull on the lever N, and

lso that when the'stepped projection 7a, of the lever l?, is released from -hold on the slotted bar M, the beltshifter is shot by the spring R, to throw the drivingbelt'on to the loose pulley h. This occius whenever any one or more of the weights G drop, through breakage of the yarns by which'they are suspended, or whenever the spools carrying said yarns run out, said weight or weights,'in dropping, striking the board H of the the arm or lever J to project forwards the bar K, so that the projection j, of the drumv L, in revolving, lifts such bar-end ofthe balanced frame, and, bythe arm or lever K striking Aand lifting the lever P, disengages the latter levei'liom the slotted bar M, when the spring R, pulling on the lever M, operates the belt-shifter to change the driving-belt from the fast pulley h to the loose pulley h', and so stops the machine, or throws the yarn-beamout of gear.

What is here claimed, and desired to be secured by LettersV Patent, is-

In'combination with the weights G, suspended on or from the yarns, the balanced frame H, I, J, and K,

arranged for operation by said weights, revolving shaft Vor drum L, provided with a lifter, f, and belt-shifter,

for throwing the yarn-beam out of gear, all for action together, substantially as speciiied.
